QR Phishing - Quishing
What is it and how can we defend against it.
QR phishing, also known as quishing, is a type of cyberattack where attackers use QR codes to trick victims into visiting malicious websites or downloading harmful content. As QR codes have become more popular for contactless transactions, menus, and quick access to websites, cybercriminals have started exploiting them as a new phishing vector.
Here's how it works:
- Creation of a Malicious QR Code: The attacker generates a QR code that links to a fake or malicious website.
- Distribution: The QR code is placed in public areas (e.g., posters, flyers, restaurant tables) or sent via email, text messages, or social media.
- Deception: The QR code may appear to lead to a legitimate site (like a bank, delivery service, or login page), but actually redirects to a phishing site.
- Exploitation: Once scanned, the victim may be prompted to enter sensitive information (like login credentials or credit card numbers) or unknowingly download malware.
Why QR Phishing is effective:
- Trust in QR codes: Many people scan QR codes without verifying their source.
- Hard to detect: Unlike links in emails, QR codes don’t show the URL until after scanning.
- Mobile-focused: Most QR codes are scanned using smartphones, which may lack strong security protections or URL previews.
How to protect against QR Phishing:
- Be cautious with public QR codes: Don’t scan codes from unknown or suspicious sources.
- Preview the URL: Some QR scanner apps allow you to see the URL before opening it – use this feature to verify the link.
- Use trusted apps: Only scan QR codes using reputable apps that offer security features.
- Avoid entering sensitive info: Don’t input personal or financial information on websites opened from QR codes unless you’re sure of their legitimacy.
- Educate users: Awareness is key – understanding the risks helps prevent falling for these scams.
QR phishing is a growing threat in the digital landscape, especially as QR codes become more integrated into everyday life. Staying alert and verifying sources before scanning can help you avoid becoming a victim.
